BICI-IARD' O. WIPPERMAN, OF CHICAGO, ILLINOIS.

STUIVIP-PULLER.

Application led May 26, 1911.

T0 all whom t may concern.'

Be it known that I, Bici-IARD O. VVIPPER- MAN, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new, and useful Improvements inStump-Fullers; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the numbers of reference marked thereon,which form a part of this specification.

Stump pulling machines are usually exceedingly cumbersome. The enormouspower required for such uses has usually been attainable only throughthe use of an exceedingly strong supporting frame or shear mounted uponwhich are the mechanisms 0f various kinds used for the purpose ofdelivering the power from a motor or draft animals in such a manner asto attain the purpose. Owing to the exceedingly heavy construction ofsuch machines, the work is necessarily slow, which is also due to thetime required in moving from one position to another in settingpreparatory to the work.

The object of this invention is to afford a manually operated stumppuller in which only such a frame is required as may be necessary tosupport the mechanism in moving the same from place to place and inwhich no part of the stresses exerted by the machine at workiscommunicated to a supporting frame.

It isv an ob] ect of the invention to afford a construction in whichsuitable tackle is installed between the stump to be pulled and asuitable anchorage and whereby an operator standing opposite themachine, may operate the same manually to attain thereby much greatereffective results than has heretofore been attainable even by the largermachines.

It is an object of the invention to afford a machine in which the timeconsumed in the setting of the machine is reduced to a minimum and inwhich it is only necessary to connect the mechanism with the stump to bepulled and with a suitable anchorage and wherein the only frame used isthat afforded by the relatively light hand truck whereby the mechanismis moved from place to place.

The invention embraces many novel features and consists in the mattershereinafterV described and more fully pointed out and defined in theappended claims.

with the frame or truck omitted. 'Fig' 8 is an enlarged vertical sectiontaken through the gear. Fig. 9 is a side elevation of the multiplyinggear with the casing or cover removed. Fig. l0 is a section online 10-10of Fig. 8. Fig. 11 is an enlarged side elevation of the equalizing gear.

As shown in the drawings: A portable hand truck comprising side framemembers l and 2, is supported upony wheels 3, by means of an axle 4,near the lowerend of said frame members, and brace bars 5, are plvotallysupported on the inner and the outer side of each of said frame membersl and 2, and are ladapted to swing outwardly, as shown in Figs. 1 andel, to support said frame in upright position when at work, and areadapted to swing inwardly and to be engaged in such inward position whenthe frame is swung downwardly to permit the same t0 be rolled vupon itswheels to the next position or setting. Extending across said frame atthe top thereof, is a shaft 6, having a chain sprocket wheel 7, thereon,and extending across the frame near the middle thereof is acorresponding shaft 8, also having a sprocket wheel 9,

as shown, a frame plate 11', and a casing l2,

spaced therefrom and having an upwardly extending boss 13, through whichand through a corresponding boss on the top of the frame plate extendsthe expansion shaft 14, wherein the gear is suspended in said link. Saidcasing V12, is` provided with a peripheral flange on its outer side, asshown in Figs. 8 and 9, and saidflange is provided with inwardlydirected gear teeth affording an internal gear 15. Journaled in saidyframe plate 11,` and the casing 12, at the axis thereof, is a chainsprocket wheel 16, rigidly secured onor integral with the tubular shaftor sleevev 17 andv 18, which are journaled respectively in the casingand in said frame plate to rotate therein. Ex tending axially throughsaid gear and the tubular shaft therefor, is a shaft 19, secured on theouter side of which `beyond the frame platel 11, is a large chainsprocket gear 20, in alinement with the chain sprocket gears 7 and 9, onthe shafts 6 and 8 respectively, and trained about said chain sprocketgears is an endless chain 21, as shown in Fig. 5, and which is ofsuflicient length to afford a convenient amount of slack between thesprocket wheels 9 and 7, and at the rear side of the machine, or, inother words, between the machine and the anchorage. Secured on theopposite end of said shaft 19, is a pinion 22, of small size, whichmeshes with gear wheels 23, on opposite sides thereof, journaled in aspider or frame 24 and 24a, and concentric with the casing and rigidlysecured to, and integral with which are relatively small pinions 25,which mesh with the internal gear 15, before described. Said innerspider or frame member 24a, is rigidly keyed on the shaft 17, for thepower chain sprocket wheel 16, to rotate the same. As shown, a gearcover or casing 37, is secured on the casing 12, to inclose the gears toprotect the saine from dirt and dust. e

` Pivotally engaged upon a lug 26, on the Y side of the casing and atthe rear of the sprocket Wheel 16, is a rearwardly directed link 27, andconnected with Awhich is a spreader bar 28, which at its opposite end ispivotally `engaged on a yoke 29, which Y projects forwardly between theframe bar 1, and the casing, and journaled between the arms of which isa lchain sprocket wheel 30. Links 31, extend from the opposite ends ofthe spreader bar rearwardly and are connected by means of any suitableclevis,

i 1* shackle or toggle 32, with the anchor chain 33, which is engagedabout any object such as a growing tree, or may be even attached to adead man buried in the ground to afford sufiicient anchorage. 1

The machine is made fast to the stump o object to be moved by means of asuitable sling 34, which may, of course, be attached directly to thestump or to a lever lashed y thereto, as preferred, or in any manner toeffectively apply the power.

p Connected in said sling is a tackle block, as shown, a.sin gle blockor chain sheave 35. One end of the power chain 36, is connected with`the strap or eye of said block and the chain is led around the sheave30, in the yoke 29,

thence back and through the block 35, thence around the smaller sheave16, and the fall or end thereof is attached to the chain returning tothe block 35, thus affording a vpractically endless chain to enable themovement of the chain toward the block 35., to take up the slack of thechain from the chain sheave 16, which is substantially of the same size.

The operation is as follows: Having connected up the machine with thestump to be pulled and with a suitable anchorage, as shownin Fig. 1, theoperator stands between the machine and the anchorage facing the stump,and pulls upon the power chain 21, thereby rotating the large powersprocket wheel 20, and thereby the shaft 19. This rotation iscommunicated by the pinion 22, to the gears 23, and thence to thepinions 25, which mesh with the stationary internal gear 15. Inconsequence, the internal frame or spider in which the gear wheels 23,are journaled is forcedk to rotate upon its axis driving thereby thepower sprocket wheel 16, about which the fall of the chain 36, istrained. As the chain is drawn through the block 35, and sheave 30, thestress exerted is multiplied enormously owing to the successivereductions in speed of the drive afforded from the construction beforedescribed, and in consequence a proportionally greater pulling effect isattained at the stump or object to which the pulling stress is applied.`inasmuch as the end of the fall is attached tothe outrunning lead ofchain passing through the block 35, it follows that the slack is takenup as rapidly as produced by the movement of the outgoing lead of chain.In consequence, a second operator is not required, and one man operatingthe power chain 21, may readily develop sufiicient energy at the block35, to serve the purpose for which the machine is designed, that is tosay, to pull practically any stump. @f course, the power applied mustdepend to an extent, upon the size of the large power sprocket wheel 20,and the relative sizes of the remaining sporcket wheels and gear wheelsfor driving the saine. l/Vhatever the power exerted, however, no stresswhatever need be exerted upon the truck, inasmuch as the only weightsustained thereby is merely the weight of the mechanism which is free toswing upon the clevis 10. When the work is accomplished, the machine maybe almost instantly moved to another setting, for this purpose it beingonly necessary to release the sling and release the anchor chain, swingthe braces inwardly to the frame at one side the machine, swing theframe downwardly to a nearly horizontal position and load the chainsthereon, when the machine may be moved by the operator upon its ownwheels to the next position or setting, where, of course, the operationmay be repeated as before described.

Of course, details of the construction may be varied. 1 therefore do notpurpose limiting the patent granted on this application otherwise thannecessitated. by the prior art.
